Why did glass jars figure so largely in Tesla's life during his radio research?

To use the vernacular: do you think Tesla was "looney"?... Defend your answer.

Nikola Tesla had some behaviors that can certainly be viewed as symptoms of insanity. Do you think the inventor suffered from mental illness? If so, do you feel he should have had it treated, why or why not?

Agree or disagree with Tesla's hypothesis that he could use machinery to "split apart the Earth like an apple" using resonance that he was able to produce in his laboratory.
